Turning a 94 fwd stock galant into a 6g72tt awd

[Hooman_TEH]

Hey everybody
i live in Tehran and i own a 94 Galant. everything stock. i want to start a project on my old beat up of a car and turn it into my own-built custom ride. things that i have in mind are :
1- A 6G72TT . want to replace one of the TD04s with a TD05 .
2- Installing a wet nitrous kit
3- turning it from FWD to AWD
4- Invader Body Kit
5- Some changes to the interior
I'd appreciate everybody's advice on "HOW TO"s , especially about buying and installing the AWD system.
Also , if anybody here has ever installed a 6G72TT on a 94 Galant , i could use some advice on how to install it and what has to be changed and fabricated to install this engine on a 7G galant.

Why not put the 6g72 in the galant that came with the twin turbo awd 6g12 which is the 7th gen.? The 8th gen had the 6g13. That would obviously be the easiest.. Most of the 72 guys are now running 74's the 3.5L.

He's referring to the 6G72TT out of a VR-4, not the eclipse and Galant 6G72.

 

[Hooman_TEH]

yep , i am referring to a 6G72TT from a 3000GT VR4.

 

[3kgt2nv]

I come from the vr4 platform and also agree that it would be several thousand dollars cheaper to start with one of the twin turbo galants from the start since you will have the awd and engine already for it. for the cost of the td05 swap on the 6g72 its pointless since most of the td05 setups that might fit the smaller engine bay (16g) you can make the same power with cheaper bolt on turbos that are smaller 19t's and dr750's

as for the awd setup no idea about that it would most likely be total custom fab since the galant 68.1 inch wide where the vr4(gto/3000gt) is 72.4 inches wide.

i would try to source the 94 2.0 tt galant shell and look how hard it would be to stuff a bigger motor in.

personally i would keep the 2.0 and build a huge single turbo monster vs the tt v6

less weight up front and cheaper / fewer parts

 

[Hooman_TEH]

thx for the info. yep , it is going to be hard to get that engine into a 7G engine bay , but it isn't impossible , since it has been done before.
As you said, most guys here go for a 4G63T out of an EVO3 and install it on a 7G. it actually fits right in. But, i like the challenge of fitting a huge engine in the engine bay of 7G.
Can i just use an AWD out of a 94 VR4 Galant and make it work with the new AWD transmission and engine ?
FYI , there are no 7G VR4 or 7G 6A12TT in Iran and actually , all the 94 models here have carburetor and are not FI. but there is VR6 model of the 7G galant with a naturally aspirated 6A12 which is FWD. if they were , of course i would have chosen with one of them.
Thanks again for the help

biggest issue i can foresee is with the trany/transfer case and drive shaft. the drives haft would be custom i thing because of the different spline count on the output side of the vr4 transfer case and the length. it will need to be shorter and rebalanced and a careful eye to make sure it doesn't have vibration or binding issues because of the three piece design to allow for the bends it normally makes on the vr4. the rear end if you can get a galant awd rear i think would be the same procedure for doing an awd swap on an eclipse as all the fabwork of adding the posts to hold the sub frame would be similar so i would look into those how to threads. also look on 3si.org about doing a awd swap on a fwd nt 3000gt/gto

it looks like to even attempt this your going to need a complete parts vr4 since you will need the wiring harness and ecu as well as the engine trans and rear diff as well as a bunch of other parts.

being different is rewarding but why if you dont mind me asking dont you just build a vr4 or get a gto(rhd) even the base non turbo gto from japan come awd

 

[Hooman_TEH]

Of course i wouldn't mind. Actually , i wanted to go with a FWD and a custom 4G64T DOHC. But i thought to myself , if i am going to spend 10 grand on this , might as well put a 6G72TT for a bit extra and have a 6 cylinder instead of a 4 and with a bit of modifications, i can have a monster in the engine bay. I could go with a FWD 6G72TT , but there will be a lot of power loss at take off and gear change + it would put a lot of pressure on the front wheels and trany.

im not a hater or a nay sayer buts in infinitely cheaper and easier to make power and there is alot more proven setups for the 4 series motor than there are for the 6g72. they are just starting to hit the growth of their platform and all the research is being done at the expense of the owners.

with a 4-6k investment you can make 400-500 hp with the 4 series. with the same investment it will prob buy you all the stock 6g72 parts you will need for the job not including any fab work or upgrading. and since your buying it as a prats car you will have no idea if anything works. vr4's have tranny and transfer case issues just like dsms.

This. While I think the idea of a 6g in an AWD Galant would be very cool, it's not exactly cheaper, easier, or better. Using the AWD setup from a GVR4 mated to a DOHC 4g64 would be a better route to go IMO. Not trying to shoot down your idea because it is really cool, the 4g platform is just more practical for making big power. Which is why we haven't all sold our DSM's for 3000gt's.

 

[Hooman_TEH]

You definitely got a point there. I might just go with a custom 4G63T after all. but there is a problem. in 94G , the timing belt is on the driver's side, so i can only use a 4G63 out of an EVO3. which i think is a little bit too old compared to the MiVEC 4G63Ts now in use in the latest generations.

all the 1st and second gen dsm's have the timing belt on the drivers side also.

mivec is newer tech and does flow better but there are more fast 1st and 2nd gen dsm's out there than there are late generation evos with the newer head style.

there is a guy on the 3000gt forum 3si.org screen name itialiangrasso that adapted a set of mivec heads from 4th gen eclipse v6 to his 6g72 block that makes like 730hp at like 18 psi.

 

[BoostedPhoenix]

He is located in another country, Though im not familiar with how the DSM's were distributed, i'm fairly certain he has a better chance finding an early EVO in the junkyard than he is a DSM where he is at.

 

[Hooman_TEH]

Finding is not a problem . i can get anything i need from Canada or even US, let alone japan , UAE or ...
Thx for help everyone. after all i really like the 6G72TT challenge . i think i am gonna go with a 6G72TT and mod it a little bit. for now with FWD with a wider set of wheels and bigger rims. Though i will need all the help i can get for this project of mine. after that i am gonna go with a customized AWD out of a 94 VR4 to minimize the power loss at take off. fortunately i work in the metal.related industries , so making custom shafts wouldn't be a problem.

 

[3kgt2nv]

if your going to start fwd and switch to awd i would source an awd tranny and transfer case in the beginning and just leave the transfer case and driveshaft out if it will work without wrecking the tranny.

i know the trannies in 3000gt are $$$ since there are so few rebuild parts so its usually a replace option if anything goes wrong with them.

I know when i exploded a shift fork hot lapping mine at the national gathering in 2008 a used tranny was 1600 and that was a good deal for a 6speed tranny. the 5 speeds are a little cheaper but are usually more beat up.

 

[Hooman_TEH]

Hey , i am back.
after researching this a bit more , i found out that the 6G72TT in a 7G galant is possible , but man it's hard to stick it in there ! the front axle has to be shortened . the drive shaft has to be shortened as well . let alone i have to build a custom Adapterplate for the gear box to be bolted on . i will have to customize the AWD and .....
So , the whole 6G72TT idea is bye bye . i will wait for the next project and install a 6G72TT on an AWD 8G galant.
For now and the 7G project , i have a couple of questions. which engine can be bolted directly on a 7G engine mounts ? 4G63 alone , or 4G64 is a direct mount too ? which engine would be a better choice ?
Thank you for helping me out guys

P.S : to anyone who has this idea after me and is looking for a source to find out how to get this done, don't bother. this is doable, but not practical. if you really want a 6G72TT , get an 8G AWD galant and install it on that.

 

[WES_393]

Yes, the Evo 1-3 and DSM style 4g engines will fit in a 7g galant. The only questionable part would be whether the engine will bolt up to the trans. I imagine it wouldn't be impossible considering the 4g64 is originally a Galant engine, not a DSM engine. I would definitely go with a DOHC 4g64 if you can.

Here is a 7g Galant with a 4g64 SOHC.

the engine in that picture minus the injection rail and headers , looks exactly like the engine of my own car !!!!! look at the picture i posted earlier and you will see .
So , i should either go with a 4G63T from an EVO3 , or a DOHC 4G64 that has been turbo charged. i can change the transmission to something else that fits galant , like an eclipse transmission to go with the engine.

You could just pull your engine out, throw some forged rods and pistons in it, bolt on a 4g63 head, and build your own turbo system.

I also feel the 4g63t would be best, but as far as the 6g72tt as ive built a few 4-6k investment will net you 500-600hp, last dd i had $1500 turbos $700 in fuel pump inj/controler, $1000 in exhaust, $1000 with cam gears crank pully and flywheel, and i made 383awhp@5900 396awtq@2700 and in drivetrain loss and thats 500ish

Yes just build the bottom end and build a 1g head bolt it on and turbo it. Even stock with the single head you can turbo it with a 16g and get a good 280ish hp and about 320 ft/lbs or so of torque.

most people when talking power levels/torque want the put down numbers not at the engine.

im guessing for 1500 turbos you went with 15g's and they are usually good for about 400-425 maxing the turbos out to the wheels. and whats great is if the motor is healthy the stock block will run it all day no problems. very proven set up on the 6g72

My bad on the wheel/ crank power, dr500s @ 17psi, my dr800 car put 661awhp @ 24psi stock block and heads
